Abstract : A direct relationship between conventional array design and the array performance in an adaptive mode is given. It is shown that the basic goals of conventional array design such as low sidelobes and narrow beamwidth have a direct effect on the adaptive array performance and should not be ignored. An expression is obtained showing that the output signal-to-interference-plus-noise ratio (SINR) of an adaptive array is related to the conventional pattern of the array. The above relations are illustrated for both linear and nonlinear arrays.
